This paper provides a first step in developing a system-wide stress simulation. The model incorporates several important features of the financial system. These include several types of institution (including banks and non-banks) and how their actions may propagate and amplify stress. Rather...

How to prevent runs on open-end mutual funds? In recent years, markets have observed an innovation that changed the way open-end funds are priced. Alternative pricing rules (known as swing pricing) adjust funds' net asset values to pass on funds' trading costs to transacting shareholders. Using...

Utilizing new SEC data enabling us to compute performance of mutual funds' derivative positions, we study how funds use derivatives and how derivatives contribute to performance. Despite small portfolio weights, derivatives significantly impact funds' leverage and contribute largely to returns...

This paper studies the trading behavior of U.S. actively managed equity mutual funds during the COVID-19 market crash. We show that Environmental, Social, and Governance (ESG) funds helped to stabilize the market by contributing to the resiliency of ESG stocks, but interestingly non-ESG funds...

We present a comprehensive analysis of the performance and flows of U.S. actively-managed equity mutual funds during the COVID-19 crisis of 2020. We find that most active funds underperform passive benchmarks during the crisis, contradicting a popular hypothesis. Funds with high sustainability...

Some financial supervisors worry that liquidity transformation within the “shadow banking” sector might threaten financial stability. For example, a mutual fund promising overnight liquidity based on illiquid assets (such as corporate bonds) runs the risk of needing to “fire sale” some...

We document significant outperformance by government bond funds on important macro announcement days such as FOMC and GDP. The macro-day outperformance is persistent, larger during times of high macro disagreement and surprise, and stronger for active funds with larger idiosyncratic volatility....

Using proprietary monthly holdings data from Morningstar, we show that Environmental, Social, and Governance funds’ trading during the Covid-19 market crash was consistent with the choices of their clientele. Thus, ESG funds helped to stabilize the market for ESG stocks, but interestingly...

Can ETFs trigger fire sales in illiquid assets? We develop and empirically examine a model where an authorized participant (AP) holds bond inventory and connects the ETF to the underlying bond market. For redemptions, the AP acts as a buffer between the two markets, holding redeemed bonds to...
